We perform numerical simulations on heat diffusion induced by a nuclear reaction between a neutron and a Boron isotope 10B and related non-equilibrium superconducting dynamics in MgB2 neutron detector devices. The simulation results reveal that not the heat diffusion but the superconducting dynamics caused by the heat diffusion is responsible for the electrical signal. This is because the generated electrical field is directly related with not the local temperature but the phase dynamics of the superconducting macroscopic wave-function. This fact tells us how to improve the neutron detection speed.
